Sleek, slim, secure aluminium inline patio door
Perfect for small or wide-span openings
Offering it all
With the perfect combination of security, thermal performance, and style, SheerGlide® instantly transforms any home, flooding it with natural light while framing the surrounding landscape.
Proudly Made in Britain, these high-quality aluminium inline patio doors don’t just look the part, they also benefit from our unique patented thermal and security technology
Unique Single Component Interlock
Our patent pending Sheerline TwinLock interlock is strong, slim, and fully thermally broken. It’s the first of its kind and as it’s integrated into the doors, it allows them to pass both thermal and security testing without compromise.
Exceptional Security Built-in
Designed by hardware specialists, Ingenious Locks & Hardware, this modular ‘quad’ hooklock provides built-in security. A true PAS 24 lock, it is manufactured to exacting standards, delivering exceptional levels of reliable security and operation.
Featuring Thermlock Technology
Designed and manufactured by us, our award-winning Thermlock® technology offers almost double the insulation when compared to polyamide. This makes SheerGlide® inherently more efficient than systems with polyamide thermal breaks.
With refined Aesthetics
With slim sightlines and a 38mm interlock, an architecturally refined style, modern thermal performance and security excellence SheerGlide® proves that it is possible to offer style without compromising on performance
